Women can now protect their honour with the newly invented flashy nail colours.

Interestingly, the new Undercover Colors nail polish helps to prevent sexual assault by changing its colour on detecting the presence of date rape drugs like rohypnol, xanax and GHB mixed in drinks.

"While date rape drugs are often used to facilitate sexual assault, very little science exists for their detection. Our goal is to invent technologies that empower women to protect themselves from this heinous and quietly pervasive crime," a statement appeared on the company's official Facebook page, read.

"With our nail polish, any woman will be empowered to discreetly ensure her safety by simply stirring her drink with her finger. If her nail polish changes colour, she'll know that something is wrong".

Four students from the North Carolina State University, US - Tyler Confrey-Maloney, Ankesh Madan, Stephen Gray and Tasso Von Windheim are the brains that worked behind the ground - breaking invention.

"As we were thinking about big problems in our society, the topic of drug-facilitated sexual assault came up. All of us have been close to someone who has been through the terrible experience, and we began to focus on finding a way to help prevent the crime," inventor Madan, told Higher Education Works.

"We wanted to focus on preventive solutions, especially those that could be integrated into products that women already use. And so the idea of creating a nail polish that detects date rape drugs was born."

The product that won the Lulu eGames student competition in this summer has already entered the semi-final round of K50 Startup Showcase.

It will take some more time to hit the market as the founders are still under the process of improving their product.

Sexual violence against women is a serious issue that haunts the whole world. At least 35 percent of women in the world are victims of either intimate partner violence or non-partner sexual violence, according to the World Health Organization (WHO).

Meanwhile, India has always topped in rape cases. UN Crime Trends Survey 2010, released in July ranked India (22,172) in the third position after the United States (85,593) and Brazil (41,180) - in rape cases around the world.

The National Crime Records Bureau (NCRB) report released last month found that about 93 women were being raped every day in India.

The report also found a major rise in the number of cases reported within one year- 24,923 in 2012 to 33,707 in 2013.

Similarly, a 13-year old investigation conducted by the Commonwealth Human Rights Initiative (CHRI) reported that 2,64,130 rapes occurred in 28 Indian states within the period.
